Crafstman garage door opener with wall switch and two remotes. I
called Sears and talked to a tech who had never heard of this
particular problem... maybe someone here has experienced this.

The unit operates fine from the wall switch, but suddenly, the
remotes don't work. Nothing has been altered and remote batteries
were checked. The little light in the wall switch up/down touch pad
is blinking, whether the door is up or down, which isn't right, but why?

TIA

My doors have a momentary contact push button. A wall switch would
make contact all the time probably shorting the circuit and preventing
the remotes from working.

Surprising that no one has mentioned the hopefully obvious cause ! The
door electronic -eye sensors will cause this problem if they have been
"knocked" ever so slightly out of line. The beam not lining up will not
allow the remote openers to work and show a malfunction to the control
board! The wall button is hard wired to the opener and may by- pass
the sensor system . My best guess would be to check the sensor alignment.

My door will open no matter what the sensors are sensing, or not
sensing. They do however need to be working for the door to close.
